Therefore, the sampling distribution of x is normal. The population is either non-normal or of unknown distribution and the sample size is at least 30. Therefore, the sampling distribution of x is approximately normal (Central Limit Theore Case 2: Means). The population is either non-normal or of unknown distribution and the sample size is less than 30. Therefore, we have insufficient information to conclude that the sampling distribution Case 3: sample mean x is either normal or approximately normal. Prices for boned trout are not normally distributed, with , = $5.00 per pound and o = $0.70. A random sample of size 37 is taken. Determine whether the sampling distribution of x is normal, approximately nor unknown. The sampling distribution for the sample mean x is normal since the prices for boned trout are normally distributed. The sampling distribution for the sample mean x is approximately normal since the prices for boned trout are not normally distributed and the sample size is less than 30. The sampling distribution for the sample mean x is approximately normal since the prices for boned trout are not normally distributed and the sample size is greater than or equal to 30. The sampling distribution for the sample mean x is unknown since the prices for boned trout are not normally distributed and the sample size is less than 30. The sampling distribution for the sample mean x is unknown since the prices for boned trout are not normally distributed and the sample size is greater than or equal to 30.
